ALFRED CREIGH srEvENsoN, or OAK'DALE STATION, PENNSYLVANIA,

MEDICTED'VENTILATOR.

SPECIFICATION forming par@ 'of Letters Patent No.l $49,405, datedNovember-"5, 119.95.|

Application filed January 9, 1895.

To all whom itmay concern: Y vBeit known that L ALFRED GREIGH Sra venteda new and Improved Medicated Ventilator, of which the following is afull, clear;

and exact description.

`My invention relates to' improvements in and the object of my'inventionis to produce tilator which may be applied to any ordinary germs frombeing carried into the roognfwhich may be used merely to supply pureair, if de-v sired, Which is also adapted' to provide air laden withsuitable antiseptics or disinfectadmit the fir Without an'objectionabledraft, and which in general is adapted to form a sub- The invention isalso intended to provide an outlet for impureor overheated air.

' To these ends my invention consists of certain features ofconstruction and combina'- scribed and claimed. y

Reference is tobe hadto the accompanying drawings, forming a part ofthis specification,

correspondingparts in all the vieufs. l

Figure -1- is a front elevation of my iinproved ventilator as applied toanvindow.

Fig. l. Fig. 3 is a sectional plan on the line view of the mainperforated lbox of the ventilator. Fig. 5 is a detail perspective viewends and of the cleat to which the socket is of the cleats adapted tocarry a box-socket, and Fig.y 7 is a vieW of the angle-clip or bracketforming an adjustable bottom to the said socket.

The ventilator 1s provided With a boX 10,

long enough to4 extendacross an ordinary Window, and the box ispreferably made up ,serai No. 534,309.l @To man.)

devices, and, if desired, the ends of the box may be sealed airtightWith rubber ,or anything suitable for the purpose. i

Wit-hin the box is heid a Screeniawhichl is Wide enough to extend fromtop'to bottom of the` box, preferably at a slight incline, as

shown in Fig. 2, and this-screen is made, by

held over a stiffening-frame 13a. (See Fig. The screen may be of anysuitable material and shouldbe line enough vto prevent.` dust frompassing through the' ventilator. When de s'irethaf suitable medicamentor antiseptic may befplaced in the box, and the vapor rising from vthevsaid'medicam'C-rnt or antiseptic mingles With the atmospheric air andpasses into the room through the holes 12.

To provide Nfor the easy insertion of the antiseptic or medicament thebox is provided on its inner side with an opening 14, Which has asliding door 15, by which it may be closed.

The box ends are held in sockets 16, which .are of a general U shape incross-section and preference, in the form of a bag, so as to be bentinward at the'top to forma flange 17,

which overlaps the top of the box 10 when the latter is held in thesocket. is secured to a cleat 18, Which is adapted to be secured in therunway of the Window-frame and which is provided with a groove 19 toreceive the sash-cord. The socket `has an adjustable bottom formed of anangle-iron or bracket 20, which has in itsback a vertical slot 2l toenable it to be adjusted on the fas tening-boltQZ, by which it issecured to -the cleat 18. The bracket 20 serves as a support for thebox10, and italso serves as an abutment for the Window-sash and preventsthe sash when it is raised fronr striking with damaging effect againstthe box.

. To apply the device to a Window, the cleats 1S are fastened in -thetop of the Windowframe, at the upper end of the runways 23 of IOO -1.3into the room.

the inner sash 24, the box is placed ini the sockets, the upper sashdropped simi-- 'ciently to permit the air to pass throughathe box, andthe air will then pass through fthe perforations of the box and throughthe sieve If no medicament is used, the pure'air enters 'the room, andif the medi, ciment is used the vapor of the medicament mingles with andimpreguates the air, so that it passes into the' room in a condition tobe inhaled.

It will of course beunderstood that the ventilator may be arranged inthe runway of either sash and even at the bottom oi the 15. windowinstead of at the top without departing from the principle 'of theinvention, and it will also be seen that the construction of the box andits supports maybe departed from somewhat Without aiecting theinvention.

Having thus described my invention, I claim as new and desire to secureby Letters Patent- 1. A window Ventilatoncomprising a per- 'forated box,and cleats adapted to support the end s of the box and provided withgrooves for the reception of the sash cord, substantially as described.

2. .A ventilator, comprising a perforated I box, end sockets to supportthe same, an'd` adjustable bottoms for the sockets, substantilly asdescribed.

3. A ventilator comprising a perforated box, sockets to receive the endsof the same, said sockets being open at their lower ends, and separatebottoms projecting inwardly at the open ends of the sockets to supportthe v ends'of the box, saidbottoms being removably connected tothesockets, substantially as described. Y

4. A ventilator, comprising a perforated box formed of separable halfsections, a screen heldwithin the box, end sockets to receive the box,adjustable bottoms for the said sockets, and means for securing thesockets yin the frame of a window, substantially as ALFRED CREIGHsTEvENsoN.
